In Scala, a programming abstraction is implemented which is called as Uniform Access Principle, which states that the annotations utilized to retrieve a property of a Class is equivalent for both methods and variables. This principle was imposed forward by Bertrand Meyer. The principle simply means that the notation used to access a feature of a class shouldn’t differ depending on whether it’s a method or an attribute .
Some points to note:
- Using this Principle attributes and functions with no parameters can be accessed by identical syntax.
- The definition of a function with no parameters can be transformed to “var” or vice-versa.
- This Principle is more aligned to the object oriented programming.
Now, We know that the length of an array is a variable and length of a string is a method in the Class “String” but we accessed both of them in same way.
Here, also a variable and a method both are accessed in a same manner.
